Project: Ev3 Etch-o-Sketch
What is cool about this project is how the EV3 is programmed to draw lines exactly like an Etch a Sketch does. I decided to start this project because I thought it would be fun and interesting to make a “game” that can be played on the EV3 screen.
My project started when I brought my book, “The LEGO ® MINDSTORMS EV3 Discovery Book” by Laurens Valk to the after-school STEM program that came to Groveton and one of the instructors from WMSI said I could make a project with one of the robots in the book and write about it for the website.
The only problem I had was figuring out how to program a line to appear on the EV3 screen. I fixed the problem by searching online for a program guide and found it at LEGO.com. The most fun part of the project was getting the Etch a Sketch to work. The book did not say what the sensors were supposed to do, so I added extra “blocks” into the program to use the sensors to start the Etch a Sketch.
The Etch a Sketch was simply used as a game and to see if it is possible to make a real one out of LEGO ® Bricks. Through the process of doing the project and programming it, i learned how the Etch a Sketch is programmed and what they are supposed to do.
